Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

I have successfully used an Agilent 82357B USB adapter - there are plenty on eBay from Chinese sellers... I got NI Visa to talk to Agilent, er, Keysight IO Libraries and access a 3456A attached to the 82357B. That's the simplified version... the 82357B was on a remote system over a WiFiI link

Re: [time-nuts] FE-5680A pin 6?

That makes sense. Thanks! That’ll help when it comes time to attempt to calibrate it. In this case, I doubt the seller speaks enough English to ask. But I can look at all of the pinout variations to find one with a TX pin on that wire. > On Sep 11, 2015, at 3:59 AM, Bob Camp

Re: [time-nuts] FE-5680A pin 6?

Hi There are far more unique pinouts for the 5680 than anybody can keep track of. Three also is very little that ties the markings on the unit to a specific pinout. If you are getting -5V, my guess is that you have an RS-232 output on that pin. Normal drill is to go back to the seller and

Re: [time-nuts] FE-5680A pin 6?

I figured it out. I was counting the bottom row from the wrong end. To actually find the PPS signal I had to set my scope to one-shot triggering at a very fast timebase setting (I used 500 ns/div). It’s only 1 µs wide, but it was there. > On Sep 11, 2015, at 6:07 AM, Nick Sayer

Re: [time-nuts] FE-5680A pin 6?

Hi Nick, FE-5680A is a whole family of Rb oscillators that have in common the case and name but the functionality, connectors and inner stuff varies a lot. Some are programmable on a wide frequency margin, others has a fixed frequency output, mostly 10 MHz. The connector arrangement also

Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

I have both a chinese clone 82357b and two NI GPIB-USB-HS. If you will write your own software for aging test-equipment, my experience is that a clean NI solution with GPIB-USB-HS and NI 488.2 is a *lot* less painful than trying to get Agilent GPIB to play nice with the NI software-stack. Speaking

Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

I have one each of the HP and NI USB units, and have both sets of libs installed on the same machine. I seem to have no trouble using either. But the size of each company's download is absurd! So,ething like 800MB between them. > On Sep 11, 2015, at 5:08 PM, Tommy phone

Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

Just ordered Ethernet to GPIB from Prologix.biz for $199. They also have a USB version, which a good friend has and recommends. (Which is why I bought the ethernet device.) Can you share info on labview home and your apps? Jim wb4...@amsat.org On 9/10/2015 5:58 PM, Brooke Clarke wrote:

Have never had a problem when using the 82357A/B with Agilent/Keysight IOLibs and VEE. Maybe that's a useful clue as I am definitely not a programmer. >From Tom Holmes, N8ZM > On Sep 11, 2015, at 2:34 PM, Hal Murray wrote: > > > opronnin...@gmail.com said: >> If you

Hi: Got one of the new in box NI GPIB-USB-HS (not GPIB-USB-HS+) units on eBay. More after it arrives from China. SparkFun is out of their Inventor's kit, I'll get it when back in stock. It includes their Arduino Uno clone (probably better than a real one for less money) and the LINX (not

Hi Jim: LabVIEW Home is the full development version that normally sells for thousands of $, but for a home user sells for $50. There's some watermark on the front panel, but otherwise is fully functional. I haven't got into the Arduino because I don't like C. LabVIEW is the highest level
